RUDOLPH D. KASSING, OF ST. LOUIS, MISSOURI.

STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 450,940, dated April21, 1891.

Application filed November 22, 1890. Serial No. 372,324. (No model.)

To ttZZ whom it may concern} Be it known that I, RUDOLPH D. KASSING, ofthe city of St. Louis and State of Missouri, have invented certain newand useful Improvements in Steam-Boilers, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

My invention relates to improvements in steam-boilers; and it consistsin the novel arrangement and combination of parts, as will be more fullyhereinafter described, and designated in the claims.

In the drawings, Figure 1 is a side elevation of my complete inventionwith a portion broken awayto more fully show the construction thereof.Fig. 2 is a longitudinal section taken on the line a: a: of Fig. 1,showing the arrangement of the deflecting-walls. Fig. 3 is a verticalcross-section taken on the line 3 y of Fig. 2.

The object of my invention is to increase the heating-surface andwater-space of steamboilers without materially increasing the volume ofthe same. To achieve this construction I attach a water rib or basin tothe shell of a boiler in a suspended position.

Referring to the drawings, 1 represents a boiler with a shell 2 and aseries of longitudinal tubes 3 and a smoke-stack 4.

5 indicates the breeching of the front end of the boiler, having formedtherein a manhole 6, through which the interior of the boiler can beinspected, and all precipitated products removed therefrom.

7 represents the furnace-chamber or the place in which the heat isgenerated.

8 indicates a series of grate-bars on which the coal or fuel is placed,and 9 are door-spaces through which the same is inserted and placed inthe furnace-chamber, and 10 are doors which are adapted to inclose saidspaces.

11 indicate the side walls of the foundation for the boiler.

12 indicates the water rib or basin, which embodies my invention. Saidwater-rib is suspended directly below boiler 1, and is thereto attachedin any suitable and mechanical manner, preferably, however, by flangingthe upper surface of said water-rib and riveting it to the exterior ofthe boiler by a series of rivets 11, as shown in the drawings.

16 represents the cap of said I water-rib, which is lapped over the endof the water-rib and thereto secured by means of rivets 17. The upperedge of said cap is flanged outwardly, however, and is secured to theexterior surface of the boiler in any substantial and mechanical manner.The inclosed space of said water-rib is in communication with theinclosed space of the boiler 1, which communication is elfected by meansof elongated slot-s or perforations 18, through which the watercontained in the boiler finds an exit into the water-rib.

The water-rib 12 is provided with a series of transverse tubes 19. Thenumber, however, is indefinite, depending on the amount ofheating-surface required and also the water-space desired. The waterpoured into the boiler passes down into the water-rib and flows aroundthe tubes 19, and is there heated. The lower surface of the water-ribrests on a foundation and division wall 20.

21 indicates a mud-drum, which is secured to the water-rib in anysuitable and mechanical manner, preferably, however, by flanging theupper portion of the end of the shell of the mud-drum and securing it tothe end of the water-rib, and extending the lower portion of the shellof said mud-drum, passing the extended portion over the lower portion ofthe shell of said mud-drum and thereby substantially securing it. Saidmud-drum is in communication with the inclosed space of the water-riband also rests in a suitable depression formed in the foundation-wall.

22 indicates a cap which is secured to the end of the water-rib, and isprovided with a m an-hole 23, through which a person can pass into theinterior of the mud-drum and repair and attend to the inner structure,as desired.

24,25, 26, and 27 represent a series of deflecting-walls, which areconstructed adjacent to the sides of the water-rib and at suitable andfunctional distances apart. The heat proceeding from the furnace-chamberstrikes against deflecting-wall 24, which is arranged adjacent to thefurnace, is deflected across to the opposite side of the furnace,whereby all the heat that is generated in the furnace is caused toemerge from the furnace only on one side thereof, as shown by thearrows. Said generated heat passes in a direction toward the rear of theboiler, strikes against the deflecting-wall 25, whereby all thecalorific power is caused to pass through the front section of thetransverse tubes 19 and then emerges from said tubes on the oppositeside from deflecting-wall 25. The heat-rays that have passed through thefront section of tubes 19 and emerged from said tubes again passbackwardly in a direction toward the rear of the boiler and strikeagainst deflecting-wall 26, and are there deflected and caused to passthrough tubes 19 to the side of the furnace from which they emergedoriginally. This series of deflections is continued until all thedeflecting-walls have been passed, and then the heat strikes the backfoundation-wall 23 of the boiler and is deflected upward and caused topass through the longitudinal tubes 3, and all the heat that is notexpended by being brought in contact with the coldness caused by thewater passes out through the smoke-stack at, which is secured to thefront end of the boiler.

By the construction as herein described it can be readily perceivedthata great amount of heating-surface can be obtained without materiallyincreasing the volume of the boiler, and the entire amount of suchspaces is constructed and put together in compact form.

Having fully described my invention, what I claim is- 1. A boiler-shell,as 2, having projecting from its outer surface awater-rib, as 12, whichcommunicates with the interior of said shell and is provided with aseries of short tubes, as 19, passing transversely therethrough andarranged or grouped in separate series or sections, substantially asspecified.

2. The combination, in aboiler, of a slotted shell 2, having projectingdownward from and secured to its lower surface awater-rib 12, the ribcommunicating with the interior of the shell through the slots therein,alongitudinal base-wall 20 below the said water-rib, tubes arrangedwithin the said water-rib in separate sections or series, an inclosingwall around the said water-rib, a source of heat communicating with theinterior of the said inclosing wall on one side of the water-rib, and defleeting-walls upon the alternate sides of the water-rib between theseparate sections of tubes therein, as described.

3. A steam-boiler consisting of shell 2, horizontal tubes located in thesaid shell, a smokestack -it,secured to the same, a depending water-rib12, secured to said shell and terminating at a distance from the end ofthe shell 2, transverse tubes 19, located in and a muddrum 21 secured tosaid water-leg, deflecting Walls 24, 25, 26, and 27 for deflecting thecalorific power through said tubes, and a furnace-chamber '7, in whichthe calorific power is generated, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
